S/o dh low count/mobility

We took an at home sperm test from gnc which came back negative....we are going to have him get professionally tested and myself as well. Ttc 3+ years... I'm so afraid.. If he comes back with bad results.. What next? Is there any hope? How could I comfort him.. He will take it so badly.. Maybe it's me... I rather it be me and not him... =( he already makes comments about how he doesn't feel like a man =( ugh...
